NUnit 是个单元测试框架可以用于所有.Net语言和JUnit类似可以用来很方便进行单元测试NUnit是完全用C#语言编写而成使用NUnit您可以只需在您代码上加上简单'Attribute'就可以进行单元测试目前NUnit最新稳定版本是 2.4.8 (下载 ), 下面是来自就NUnit官方介绍:

NUnit is a unit-testing framework for all .Net languages. Initially ported from JUnit, the current production release, version 2.4, is the fth major release of this xUnit based unit testing tool for Microsoft .NET. It is written entirely in C# and has been completely redesigned to take advantage of many .NET language features, for example custom attributes and other reflection related capabilities. NUnit brings xUnit to all .NET languages.
